めめログ is a utility application designed for Android devices that allows users to check their vision using a television and a Landolt ring. The app enables users to save and review their vision test results, making it a convenient tool for monitoring visual acuity over time. To utilize features such as saving test histories or accessing the app with multiple users, a COCORO ID login is required. It is important to note that the results obtained through the app are intended as a guideline and should not replace professional eye examinations.

The application emphasizes the importance of consulting an eye care professional for accurate vision assessments and cautions users that the app’s features and content may change or be discontinued without notice. Overall, めめログ serves as a simple yet effective tool for individuals looking to keep track of their eyesight in a user-friendly manner.
